This week, I’ve sort of reverse-engineered a uniaxial composite plate from this biaxial (angled) fabric. This might seem like a waste of time, so allow me to explain: With the variation between batches of flax fiber yarn, it’s important for the “control group” to be made of the same exact fibers as the testing groups. In this case, we are testing the effect of yarn angle on strength and stiffness. So for the control group, we want to use fabric from the same exact roll as the angled fabric in our test group. Here’s what I’ve done this week:
